Q. Which of the following isomers will give white precipitate with $B a C l_{2}$ solution?

$[C o (N H_{3})_{5} S O_{4}] B r$

$[C o (N H_{3})_{5} B r] S O_{4}$

$[C o (N H_{3})_{4} (S O_{4})_{2}] B r$

$[C o (N H_{3})_{4} B r (S O_{4})]$

$[C o (N H_{3})_{5} B r] S O_{4} ⇌ [C o (N H_{3})_{5} B r]^{2 +} + S O_{4}^{2 -}$
$S O_{4}^{2 -} + B a C l_{2} \to white ppt. B a S O_{4} + 2 C l^{-}$
